  • Page 14: Export Route-Policy

    Usage guidelines When you redistribute OSPF routes into BGP on the MCE, BGP adds the configured OSPF domain ID to the redistributed BGP VPN routes as a BGP extended community attribute and advertises the routes to the BGP peer. When you redistribute the BGP VPN routes into OSPF on the BGP peer, OSPF uses the domain ID to determine whether the routes belong to the same OSPF routing domain.

  • Page 15: Ext-Community-Type

    A routing policy specified in IPv4 VPN view or IPv6 view takes precedence over that specified in • VPN instance view. If you specify a routing policy in both IPv4 VPN view (or IPv6 VPN view) and VPN instance view, the IPv4 VPN (IPv6 VPN) uses the policy specified in IPv4 VPN view (IPv6 VPN view).

  • Page 16: Import Route-Policy

    Examples # Configure the type codes of OSPF extended community attributes Domain ID, Router ID, and Route Type as 0x8005, 0x8001, and 0x8000, respectively, for OSPF process 100. <Sysname> system-view [Sysname] ospf 100 [Sysname-ospf-100] ext-community-type domain-id 8005 [Sysname-ospf-100] ext-community-type router-id 8001 [Sysname-ospf-100] ext-community-type route-type 8000 import route-policy Use import route-policy to apply a routing policy to filter incoming routes for the VPN instance.

  • Page 20: Route-Tag

    On an MCE device, you can configure a VPN route tag for a VPN instance bound to an OSPF process. The VPN route tag must be included in Type-5 or Type-7 LSAs. H3C recommends configuring the same VPN route tag for MCEs in the same area.

  • Page 21: Routing-Table Limit

    If the route tag carried in a Type-5 or Type-7 LSA received by an MCE is the same as the locally configured route tag, the MCE neglects the LSA in route calculation to avoid routing loops. Examples # Set the route tag to 100 for OSPF process 100. <Sysname>...
